View of the Isac dam and the Nantes-Brest canal from Bout du Bois

Highlight • Viewpoint

The surroundings are very quiet and with shade if necessary.

L'Isac dam on the Nantes-Brest canal

The canal offers very beautiful walks accessible to everyone with small more technical passages such as "the single hidden" near the dike. Opposite the end of wood beach is very nice too.
